To all whom t may concern.'

Be it known that we, ROBERT C. ANDERSON and FREDERICK F'. RIEE,citizensv of the United States, residing at Dayton, in thecountyofMontgomery andState of Ohio,

have invented certain new and usefuljmprovements in Exhaust ldfhistles,of which the following is a specication, reference being had therein tothe accompanying drawing. Y

Our invention l relates to signals, and in particular' to signalsattached to the exhaust pipes of automotive engines, which are operatedby the pressure'of the gases exhausting therefrom.

It is the object of our invention to provide a whistle which can beoperated by the exhaust from automotive engines and attached to theexhaust pipe thereof.

It is the further object of our invention to provide a whistle which maybe composed of two simple parts readily detachable from one anotherwithout removing the entire whistle from the exhaust pipe so that thewhistle may be cleaned of the accumulations of carbon and the like whichaccumulate in such structures due to deposits from the exhaust gases.

It is the further object of our invention to provide a simple and ruggedconstruction for controlling the exhaust of gases through the exhaustpipe and controlling them in their relation to the whistle.

It is the further object of our invention to provide means of combiningin one structure two exhaust lines and utilizing the single controlvalve for diverting the exhaust gases to the whistle of the characterdescribed.

Referring to the drawings;

Figure 1 is a section through the dual exhaust line, a single exit line,a valve and a whistle.

Figure 2 is a View partially in section showing the valve and theyielding means for returning it to its position of rest.

Figure 3 is a plan view of Figure 4.

Figure 4 is a section through the lower half of the whistle.

Figure 5 is a section through the upper half of the whistle.

Figure 6 is a section on the line 6-6 of Figure 5.

Referring to the drawings in detail, 1 is a tubular casing in whichthere is located transversely thereto, a valve shaft 2 on which Vismounted a valve consisting of the wings 3 and 4 which are joinedtogether by a hub 5 mounted on the shaft 2. This shaft has mounted onone end thereof, surrounding it, a helical spring 6. One end of thehelical spring is attached at 7 tothe l.shaft 2 and the other end isattached as atY 8 to the casing 1, so that the valve is always heldyieldingly in a given positionfrom which it is moved by the arm 9 whichis mounted on the shaft 2. This arm is connected by any suitable meanssuch as a cable to a handle adjacent the drivers seat, or may beoperated from the rearv stepfby the same method.

This casing 1 carries ai boss'lO havingthreads 11 on the interiorthereof, in whichV there is screwed the lower half of the whistle. Thislower half consists of a body 12 on which are formed threads 13 forengaging with the threads 11. This portion of the whistle has apassageway 14 therethrough which is enlarged into a chamber 15surrounded by a wall 16 on which there are provided a plurality of flatfaces 17 for engaging with a wrench, to facilitate the rotation of thewhistle when it is being screwed into the casing 1 or detachedtherefrom. The upper end of the wall 16 is enlarged and exteriorlythreaded as shown, and screwed thereonto is a collar-like internallythreaded lower end 19 of a dome 26 which forms the upper half of thewhistle. Grub screws 2O are provided for preventing casual detachment ofthe upper and lower halves from one another.

The wall 16 of the lower half has rising therefrom a plurality ofintegral standards 22 arranged at spaced intervals and formed integralwith a cap or dislr 21 Iat their upper ends. Both the cap member and thestandards are located a predetermined distance back from the outer-edgeof 16 so that when the collar 19 of the upper half of the whistle isthreaded thereon it is spaced from the cap member and its standards adistance suiicient for allowing the exhaust gases to pass through 14 and15 between the standards as at 23 and through the space between 19 and21 as at 24.

A series of spaced arch-shaped cutaway portions 25 are. provided in thedome 26 to permit of the exit of the gases to the exterior ofwthewhistle. This dome portion is hollow as at 27. The face of the cutawayportions are bevelled as at 28 and the inner edges thereof aresubstantially in line with the outer edge of the ,cap mem'- ber 2l.

While we have shown and described certain features as constituting ourinvention, it will be understood that parts have been shown for purposesof illustration only, and that we do not desire to be limited to suchdetails, as obvious modifications will occur to a person skilled in theart.

Havingthus fully described our invention, what we claim as new anddesire to secure by Letters Patent is 1. A two-part automotive exhaustwhistle comprising a lower part having a hollow attaching nipple openinginto an expanded chamber, said chamber having on its eX- terior athreaded ange, a disk above said chamber having cut away portions andsupported on legs integral with said lower portion and disk, a domescrew-threaded for attachment to said flange and having legs which whenattached to the lower portion and adjusted for use, stand opposite thelegs on the lower portion of the whistle, said disk filling said domeportion except for the cut away portions at the periphery of the disk,said dome having cut away portions above the cut away portions in thedisk.

2. In an automotive exhaust whistle, a conduit having a collar at oneend, an annular flange formed integral with and aligned with the top ofsaid collar, a plurality of spaced legs formed integral with said flangeand aligned with the outward end 0f said collar, a disk formed integralwith and aligned with, the outer ends of said legs, said disk alsohaving cutaway portions to co-operate with the spaces between said legs,a dome having a cut away portion, said cut away portion extending to thetop of said disk and aligned with the outer edge of said disk, said domeprojecting outwardly from the end of the cutaway portion and extendingto the outer edge of said flange, means for attaching said projectionportion to said flange, and said dome having ports in its cutawayportion.

In testimony whereof, we atlix our signatures.
